Answer:
(x, y) =(-4,10)
Step-by-step explanation:
6x+2y=-4
3x+2y=8 /*(-1)
6x+2y=-4 (1)
-3x-2y=-8 (2)
6x+2x=-4
(1)+(2) 3x=-12
6x+2x=-4
x=-12/3
6x+2y=-4
x=-4
6*(-4)+2y=-4
x=-4
-24+2y=-4
x=-4
2y=-4+24
x=-4
2y=20 y=20/2 y=10
(x,y)=(-4,10)
Answer:
the sales tax percent is therefore: 7.75%
Step-by-step explanation:
The sales tax she paid is $69.75, for a sofa whose sale price is $899.99.
Since $69.75 is the unknown (x) percent of $899.99, then we write this statement in math terms as:
69.75 = x * 899.99
solving for x we get:
x = 69.75 / 899.99
x = 0.0775
this is the decimal form of the percent, and in order to write it as percent, we multiply it by 100:
the sales tax percent is therefore: 7.75%
